Dual Flush Valveĭual flush valves, like the tower- or canister-style flush valves, sit directly on top of the tank-to-bowl hole. This design produces a 360-degree flow through the base of the toilet tank into the toilet bowl, allowing you to increase the effectiveness of the flush without increasing the size of the toilet flush valve. Rather than a fragile hinged flapper that is a common breaking point for standard flush valves, these flush valves employ a vertical flapper that sits directly underneath the overflow tube. Canister) Flush ValveĪ tower-style or canister-style flush valve can come in several sizes, depending on the toilet. Beyond this size difference, the style and way that the valve works is exactly the same as standard and 3-inch flush valves. The standard 4-inch flush valve is intended for toilets with a tank-to-bowl opening of about 4 inches-a bump in size that provides a more powerful flush as the flow of water into the toilet bowl increases. The larger opening allows more water to flow into the tank at a faster pace, which can give the toilet a more effective flush to ensure that users need not double flush. The design of a 3-inch flush valve is the same as that of a standard flush valve but is made for toilets with a 3-inch opening in the base of the tank. The seat of the flush valve has a large plastic bolt that goes through the hole in the tank bottom to fasten the flush valve to the tank with a large plastic bolt that must be secured from the underside of the tank. The flapper sits in the seat of the flush valve at the bottom of the toilet to stop water from flowing through to the toilet bowl. This style of toilet flush valve consists of a hinged flapper that attaches directly to the base of the overflow tube and also attaches with a chain to the top of the overflow tube. The most commonly found type in residential homes, it is the least expensive and most frequently purchased toilet flush valve. Standard ValveĪ standard toilet flush valve is 2 inches in size and works with most low-flow toilets and older toilet models.

Toilet flush valves come in the following formats: standard, 3-inch, 4-inch, tower-style (also called canister-style), and dual flush valves.

To tackle a replacement repair, you may wish to familiarize yourself with the types of toilet flush valves and their various features. This involves either matching up the size and type of flush valve that you currently have or finding a different type of flush valve that is compatible with your toilet. The best toilet flush valve for your home depends on the compatibility of the new flush valve with your current toilet. Replacing a toilet flush valve is a plumbing or toilet repair many DIYers seek to take on. If the flush valve is functioning correctly, the coloring will remain in the tank, but if the color seeps into the toilet bowl, the valve is leaking. To find out for sure, squeeze a few drops of food coloring in the tank. If your toilet constantly or intermittently runs (making that annoying hissing sound), or the tank is slow to fill, the flush valve may be on the fritz. Sitting next to it in the tank is the toilet fill valve, which is responsible for filling the tank after the flush valve has emptied it. A toilet flush valve-one of the two major components in the toilet tank-consists of an overflow tube, a toilet flapper (with attached chain), a rubber seal or gasket, and a circular base where the flapper sits to stop the flow of water from the tank to the bowl.
